"This race has now become a two-man race. There are only two candidates that have any plausible path to winning the Republican nomination, to winning the 1,237 delegates necessary to be the Republican nominee," Cruz said.

Cruz spoke on a variety of issues -- from jobs to immigration.

"We have seen so many American's lose their lives because this administration refuses to enforce our immigration laws, because this administration releases hundreds of thousands of criminal, illegal aliens. It releases hundreds of murderers," Cruz said.

"He's got a plan for America. We trust him. We believe in him. He's a proven leader in the Senate," said Lee's Summit resident Laurel Morton.

"I've followed Cruz's campaign for a long time. So as he talks to us, and he talks about the future and he tells us what he's going to do, I believe him," said Michael Hayburn, of Higginsville.
